The plugin I've been working on is now in beta. This is DebuffVitals, and it intends to help player track mob/boss health, morale, and effects available. The target audience is raiding and instance players.

I also highly appreciate a code review focused on technical problems like memory leaks, stupidity, and "that doesn't work the way you think it works". Please find the project at github on https://github.com/grimmerthan/DebuffVitals
